[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0032] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0033] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0034] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0035] Figure 1A A schematic diagram of an exemplary system architecture 100A to which the technical solutions of the embodiments of this application can be applied is shown.

[0036] like Figure 1A As shown, system architecture 100A may include terminal device 101A (the terminal device may be one or more of a smartphone, tablet, laptop, or desktop computer), network 102A, and server 103A. Network 102A is used as a medium to provide a communication link between terminal device 101A and server 103A. Network 102A may include various connection types, such as wired communication links, wireless communication links, etc.

[0037] It should be understood that Figure 1AThe number of terminal devices 101A, network 102A, and server 103A shown is merely illustrative. Depending on implementation needs, there can be any number of terminal devices 101A, network 102A, and server 103A. For example, server 103A could be a server cluster composed of multiple servers.

[0038] In one embodiment of this application, server 103A obtains an advertising recommendation request, which includes a user's blockchain identifier. This blockchain identifier corresponds to the user's identity, allowing server 103A to identify the user based on the blockchain identifier. When a user uses a new device without browsing history, their identity can also be confirmed based on the blockchain identifier. Server 103A can retrieve user information from the blockchain based on the user's blockchain identifier. This user information can come from the advertising recommendation system or other applications. Targeted advertisements are selected and recommended based on this user information, enabling accurate advertising recommendations to the user. Furthermore, since user information in the blockchain is immutable, the validity of the user information is guaranteed, further increasing the accuracy of advertising recommendations to the user.

[0039] It should be noted that the advertising recommendation method provided in this application embodiment is generally executed by server 103A, and correspondingly, the advertising recommendation device is generally set in server 103A. However, in other embodiments of this application, terminal device 101A may also have similar functions to server 103A, thereby executing the advertising recommendation method provided in this application embodiment.

[0040] Figure 1B A schematic diagram of an exemplary system architecture 100B to which the technical solutions of the embodiments of this application can be applied is shown.

[0041] like Figure 1B As shown, the system architecture 100B may include a terminal device 101B (the terminal device may be one or more of a smartphone, tablet, portable computer, or desktop computer), an advertising recommendation system 102B, and a blockchain system 103B.

[0042] Terminal device 101B sends an advertising recommendation request to advertising recommendation system 102B. The advertising recommendation request includes the user's blockchain identifier. Advertising recommendation system 102B obtains user information from blockchain system 103B based on the user's blockchain identifier. After obtaining the user information, advertising recommendation system 102B selects target advertisements based on the user information and sends them to terminal device 101B, thereby achieving accurate advertising recommendations for users.

[0043] It should be understood that Figure 1BThe number of terminal devices 101B, advertising recommendation system 102B, and blockchain system 103B shown is merely illustrative. Depending on implementation needs, any number of terminal devices 101B, advertising recommendation system 102B, and blockchain system 103B can be included.

[0044] Figure 1C A schematic diagram of an exemplary data sharing system 100C to which the technical solutions of embodiments of the present invention can be applied is shown.

[0045] See Figure 1C The data sharing system 100C shown refers to a system for data sharing between nodes. Each node 101C, during normal operation, can receive input information and maintain the shared data within the data sharing system 100C based on the received input information. To ensure information interoperability within the data sharing system 100C, information connections can exist between each node 101C in the data sharing system 100C, allowing information transmission between nodes 101C. For example, when any node 101C in the data sharing system 100C receives input information, other nodes 101C in the data sharing system 100C obtain the input information according to a consensus algorithm and store it as data in the shared data, ensuring that the data stored on all nodes 101C in the data sharing system 100C is consistent.

[0046] Each node 101C in the data sharing system 100C has a corresponding node identifier. Furthermore, each node 101C can store the node identifiers of other nodes 101C within the data sharing system 100C. This allows for the subsequent broadcasting of generated blocks to other nodes 101C within the data sharing system 100C based on the node identifiers of the other nodes 101C. Each node 101C can maintain a node identifier list as shown in the table below, storing the node name and node identifier in this list. The node identifier can be an IP (Internet Protocol) address or any other information that can be used to identify the node. Table 1 uses IP addresses as an example only.

[0047] Node Name Node identifier Node 1 117.114.151.174 Node 2 117.116.189.145 … … Node N 119.123.789.258

[0048] Table 1

[0049] Figure 1D A schematic diagram of a blockchain that can be applied to one embodiment of this application is shown.

[0050] Each node in the data-sharing system 100C stores the same blockchain. A blockchain consists of multiple blocks; see [link to relevant documentation]. Figure 1D A blockchain consists of multiple blocks. The genesis block includes a block header and a block body. The block header stores input information feature values, version number, timestamp, and difficulty value, while the block body stores the input information. The next block after the genesis block takes the genesis block as its parent block. The next block also includes a block header and a block body. The block header stores the input information feature values ​​of the current block, the block header feature values ​​of the parent block, version number, timestamp, and difficulty value, and so on. This ensures that the block data stored in each block is related to the block data stored in the parent block, guaranteeing the security of the input information in the blocks.

[0051] Figure 1E A schematic diagram of new block generation in a blockchain that can be applied to one embodiment of this application is shown.

[0052] When generating the individual blocks in the blockchain, see Figure 1E When a node in the blockchain receives input information, it verifies the input information. After verification, it stores the input information in a memory pool and updates its hash tree used to record the input information. Then, it updates the timestamp to the time the input information was received and tries different random numbers multiple times to calculate the feature value, ensuring that the calculated feature value satisfies the following formula:

[0053] SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x)) <TARGET

[0054] Wherein, SHA256 is the feature value algorithm used to calculate the feature value; version (version number) is the version information of the relevant block protocol in the blockchain; prev_hash is the block header feature value of the parent block of the current block; merkle_root is the feature value of the input information; ntime is the update time of the update timestamp; nCits is the current difficulty, which is a fixed value for a period of time and is re-determined after exceeding the fixed time period; x is a random number; TARGET is the feature value threshold, which can be determined based on nCits.

[0055] Thus, when a random number satisfying the above formula is calculated, the information can be stored accordingly, generating a block header and a block body to obtain the current block. Subsequently, the node where the blockchain resides sends the newly generated block to the other nodes 101C in the data sharing system 100C according to the node identifiers of the other nodes 101C in the data sharing system 100C. The other nodes 101C verify the newly generated block and add it to their stored blockchain after verification.

[0056] In one embodiment of this application, the input information stored in the data sharing system 100C may be user information and / or user profiles.

[0057] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0058] Figure 2 The flowchart illustrating an embodiment of an advertising recommendation method according to this application is shown in the schematic diagram. The execution entity of the advertising recommendation method may be a server, for example, a... Figure 1A The server shown is 103A.

[0059] Reference Figure 2 As shown, the advertising recommendation method includes at least steps S210 to S230, which are described in detail below:

[0060] In step S210, an advertising recommendation request is obtained, which includes the user's blockchain identifier.

[0061] In one embodiment of this application, the ad recommendation request may be initiated by the user client application to the ad recommendation system, so that the ad recommendation system selects target ads and pushes them to the application that initiated the ad recommendation request.

[0062] In one embodiment of this application, the advertising recommendation system may obtain user authorization before obtaining an advertising recommendation request. Only after obtaining user authorization can the system obtain the user's blockchain identifier, so as to ensure the security of user information stored in the blockchain.

[0063] In one embodiment of this application, before a user client application sends an ad recommendation request to the ad recommendation system, it can first obtain user authorization. Only after the user agrees can the ad recommendation system push the ad to the user.

[0064] In one embodiment of this application, a user's private key can be generated for the user through a blockchain based on the user's registration request; the user's private key is encrypted to obtain the user's public key; and the user's public key is encrypted to obtain the user's blockchain identifier.

[0065] In one embodiment of this application, a user's private key can be randomly generated for the user through a blockchain based on the user's registration request; the user's public key can be obtained by encrypting the user's private key using an elliptic cryptography algorithm; and the user's blockchain identifier can be obtained by hashing the user's public key.

[0066] In one embodiment of this application, the user's blockchain identifier can be the user's public key or the user's private key.

[0067] In one embodiment of this application, the advertising recommendation system can obtain user information corresponding to the user's blockchain identifier from the blockchain through the user's blockchain identifier, and then recommend advertisements to the user based on the user information stored in the blockchain, so as to achieve more accurate advertisement recommendations to the user.

[0068] In one embodiment of this application, a registration electronic prize is sent to the user based on the user's registration request to incentivize the user to join the blockchain.

[0069] In one embodiment of this application, the user's registration request may carry registration information. Encouraging users to join the blockchain can increase the registration information in the blockchain, thereby increasing the user information generated based on the registration information in the blockchain, and thus more accurately recommending advertisements to users.

[0070] In one embodiment of this application, the user's registration information carried in the user's registration request may include name, gender, geographical information, age, education, family information, hobbies, occupation, mobile phone model, mobile phone number, annual income, monthly income, annual expenses, monthly expenses, etc.

[0071] In one embodiment of this application, the registration information may include the terminal identifier used by the user during registration. Information stored in the terminal can be obtained based on the terminal identifier, and this obtained information is stored in the blockchain as registration information. The registration information obtained from the terminal may include the user's shopping account, historical transaction information corresponding to the shopping account, game account, browsing history, favorites history, historical transaction records of the bank account, etc.

[0072] In one embodiment of this application, due to the widespread use of electronic payments, it is possible to obtain the user's historical transaction information stored in the user's terminal. This historical transaction information may include products purchased by the user, the amount spent on those purchases, the shopping account used for the purchases, the user's browsing history before purchasing the products, and the purchase time. Users can obtain historical transaction information obtained from transactions using their shopping accounts on the terminal, and they can also obtain historical transaction information from bank account transaction records stored on the terminal. All obtained historical transaction information can be stored in the blockchain.

[0073] In one embodiment of this application, based on the user identity information stored in different user terminals, all terminals corresponding to the user identity can be identified, the user information stored in all terminals can be obtained, and the user information and the user's blockchain identifier can be stored in the blockchain.

[0074] In one embodiment of this application, a user profile can be generated based on the user's registration request; the user profile is then stored in the blockchain along with the user's blockchain identifier.

[0075] In one embodiment of this application, a user's profile can be formed by combining registration information carried in a registration request.

[0076] In one embodiment of this application, a user profile can be formed by analyzing the registration information carried in the registration request.

[0077] In one embodiment of this application, the user profile may include user information such as occupational characteristics, family structure, consumption motivation characteristics, repurchase type, payment habits, decision-making characteristics, needs, economic situation, credit status, consumption philosophy, attitude towards promotions, awareness of a certain brand, and consumption habits.

[0078] In this embodiment, a user's occupational characteristics can be obtained from occupational analysis within the user's registration information. Occupational analysis can reveal a user's occupational characteristics, which may include whether they need to socialize or give gifts, whether they need to obtain certifications, or whether they need certain specific items. For users who need to socialize or give gifts, high-end clothing, luxury gifts, and liver-protecting health products can be recommended; for users who need to obtain certifications, reference books relevant to their profession can be recommended; and for users who need certain specific items, these items can be recommended, thus achieving more accurate advertising recommendations.

[0079] In this embodiment, a user's family structure can be obtained by analyzing the user's registration information, and can be obtained based on the number of family members and the age of family members.

[0080] In this embodiment, the user's consumption motivation characteristics can be obtained by analyzing historical transaction information from the registration information obtained from the terminal. Consumption motivation characteristics can be categorized into motivations such as beauty-related motivations and motivations for spending on family members.

[0081] In this embodiment, the user's decision-making characteristics can be obtained by analyzing historical transaction information from the registration information obtained from the terminal. This includes the number of times and duration the user browsed products, the number of returns / exchanges, etc., all within the historical transaction information. The user's decision-making characteristics can be categorized as hesitant, impulsive, or deliberate.

[0082] In this embodiment, the consumption philosophy can be derived from the analysis of historical transaction information obtained from the registration information of the terminal. Consumption philosophies can be categorized into frugal, ordinary, high-end, and luxury types.

[0083] In this embodiment, consumption habits may include consumption time, consumption location, etc.

[0084] In step S220, user information is obtained from the blockchain based on the user's blockchain identifier.

[0085] In one embodiment of this application, the user information may be registration information.

[0086] In one embodiment of this application, the user information can be user information obtained from a user profile based on registration information analysis. Since the user information in the user profile has been analyzed, recommending advertisements based on the analyzed registration information is more accurate than recommending advertisements directly based on registration information.

[0087] In one embodiment of this application, an advertising recommendation system identifier can be obtained. Based on the advertising recommendation system identifier and the user's blockchain identifier, the scope of information authorization granted by the user to the advertising recommendation system can be determined. Based on the scope of information authorization, user information authorized by the user to the advertising recommendation system can be obtained from the user's profile. User information can only be obtained after obtaining user authorization, thus respecting the user's privacy.

[0088] In one embodiment of this application, the scope of information authorized by the user to the advertising recommendation system is the scope of user information that the advertising recommendation system can obtain from the blockchain.

[0089] For example, if a user's authorization to an advertising recommendation system includes their historical transaction information but excludes their identity information, then the system can only access the user's historical transaction information, not their identity information, based on the system's identifier and the user's blockchain identifier. The user's historical transaction information is the user information authorized by the system to that advertising recommendation system.

[0090] In one embodiment of this application, the advertising recommendation system identifier can be the blockchain identifier of the advertising recommendation system, which can be generated based on the registration request of the advertising recommendation system to the blockchain.

[0091] In one embodiment of this application, an advertising recommendation system private key can be generated for the advertising recommendation system based on the registration request of the advertising recommendation system to the blockchain, the advertising recommendation system public key can be obtained by encrypting the advertising recommendation system private key, and the advertising recommendation system blockchain identifier can be obtained by encrypting the advertising recommendation system public key.

[0092] In one embodiment of this application, a private key for the advertising recommendation system can be randomly generated based on the registration request of the advertising recommendation system to the blockchain. The private key is then encrypted using an elliptic curve cryptography algorithm to obtain the public key for the advertising recommendation system. Finally, the public key is hashed to obtain the blockchain identifier of the advertising recommendation system.

[0093] In one embodiment of this application, the blockchain identifier of the advertising recommendation system can be either the advertising recommendation system's private key or its public key.

[0094] In one embodiment of this application, the user's profile and the user's blockchain identifier can be formed into information records and stored in the blockchain.

[0095] In one embodiment of this application, after obtaining user authorization, the advertising recommendation system can obtain the scope of information authorization granted by the user to the advertising recommendation system, and obtain user information authorized by the user to the advertising recommendation system from the user profile based on the scope of authorization.

[0096] In one embodiment of this application, user information authorized by the user to the advertising recommendation system, the user's blockchain identifier, and the identifier of the advertising recommendation system can be stored in the blockchain as information records.

[0097] In one embodiment of this application, after a node in the blockchain obtains an information record, it can perform a hash operation on the information record to obtain digest data, sign the digest data using its own private key to obtain signature data, generate publication data based on the node's own public key, the information record, and the signature data, and publish the publication data to the record pool of the blockchain system to wait for the information record to be written into the blockchain.

[0098] In one embodiment of this application, a node in the blockchain obtains published data from the record pool of the blockchain system. The published data includes information records, signature data, and the public key of the publisher corresponding to the published data. The signature data is obtained by signing the digest data with the publisher's private key, and the digest data is obtained by hashing the information record. The node decrypts the signature data in the published data using the public key of the publisher corresponding to the published data to obtain first decrypted data. The node also hashes the information record in the published data to obtain first data. If the first data matches the first decrypted data, a block is constructed based on the information record in the published data. The node then connects the blockchain to the blockchain and synchronizes it within the blockchain system.

[0099] In one embodiment of this application, if the authorized user information includes target user information, an electronic prize corresponding to the target user information is sent to the user to incentivize the user to authorize more user information to the advertising recommendation system.

[0100] In this embodiment, the target user information refers to user information that can significantly influence ad recommendations, and this target user information can be pre-defined. For example, obtaining only a user's name has little impact on ad recommendations, but obtaining bank account transaction information would have a significant impact. Therefore, the user's bank account transaction information can be set as the target user information. If the user's authorized information scope for the ad recommendation system includes bank account transaction information, then an electronic prize corresponding to the bank account transaction information will be sent to the user.

[0101] Continue to refer to Figure 2In step S230, target advertisements are selected based on user information for recommendation.

[0102] In one embodiment of this application, if the user information includes historical transaction information, the user's browsing history before purchasing the product can be used to obtain historical transaction information of the user's purchase through advertising, identify the types of advertisements that are likely to convert the user, and improve the accuracy of recommending advertisements to the user.

[0103] In one embodiment of this application, if the user information includes historical transaction information, the user's place of residence or work address can be determined based on the ride transaction records in the historical transaction information. Breakfast shops near the user's place of residence can be recommended to the user, and lunch and light meals near the user's work address can be recommended to the user on weekdays, thereby achieving more accurate advertising recommendations to the user.

[0104] In one embodiment of this application, if the user information includes user identity information, the geographical information in the identity information can be used to determine the products the user may need. For example, if a certain disease is prevalent in a certain region, advertisements related to that disease can be recommended to users in that region.

[0105] In one embodiment of this application, target advertisements can be selected and recommended based on user information authorized by the user to the advertising recommendation system. This approach respects user privacy while recommending advertisements to the user.

[0106] In this embodiment, if the user information authorized by the user to the advertising recommendation system only includes the user's age, then the advertising recommendation system can only select ads suitable for the user's age from the ads to be recommended as target ads.

[0107] In one embodiment of this application, a target advertisement can be displayed on the user's end, and the revenue information obtained by displaying the target advertisement can be determined. Based on the revenue information, an electronic prize corresponding to the revenue information can be sent to the user, thereby increasing the user's advertising conversion rate in the advertising recommendation system and increasing user stickiness.

[0108] In one embodiment of this application, the revenue information obtained by displaying the target advertisement may include: the revenue generated from the purchase behavior of the user through the advertisement recommended by the advertisement recommendation system, and the revenue generated after the user forwards the advertisement recommended by the advertisement recommendation system.

[0109] In one embodiment of this application, a combination of advertisements may be selected as the target advertisement.

[0110] exist Figure 2In this embodiment, by obtaining an advertising recommendation request, which includes the user's blockchain identifier (which corresponds to the user), the user can be distinguished based on their blockchain identifier. Even when a user uses a new device without browsing history, their identity can be confirmed using their blockchain identifier. User information can be retrieved from the blockchain based on the user's blockchain identifier. This user information can come from the advertising recommendation system or other applications. Targeted advertisements are selected and recommended based on this user information, ensuring accurate advertising recommendations. Furthermore, since user information in the blockchain is immutable, its validity is guaranteed, further increasing the accuracy of advertising recommendations.
